VB .NET Driver for NI PXI-5421 AWG

[William.Maier]

Hi,

I am wondering what would be the ideal way to create a basic driver for an NI instrument (NI PXI-5421) that would allow me to access some of its basic functions from within a VB .NET project.  I have been told that I could create a VI and export it as a DLL, and I would be able to access it's inputs and outputs as functions/methods from VB.  However, I suspect it may be more complicated than that.

Thanks in advance for any help.

Hi Billy,

The method you suggested would definitely work, but it does revolve around creating your VIs in LabVIEW yourself. 

Another alternative would be to use the FGEN wrapper (already built). This .NET (C# or VB) contains the NI-FGEN functions, sessions, settings, etc. within an assembly. You can just include it in your program and use the wrapper functions in the same logical manner as LabVIEW. Here are a couple of very useful links for the NI-FGEN Wrapper:

• Using NI-FGEN with C# or Visual Basic .NET
• National Instruments .NET Driver Support

Hope this helps!
